2. MURDER ON THE ORIENT EXPRESS by Agatha Christie (1934)
Snowstorms and midnight murders may have been embellishment, but Christie’s famous novel has its grounding in real-life crime. In the book, the murder of a three-year-old girl by fugitive Cassetti is based on the actual 1932 kidnap and murder of the son of aviator Charles Lindbergh. A maid employed by Mrs Lindbergh’s parents was suspected and after being harshly interrogated by police, committed suicide. But ex-convict Bruno Hauptmann was eventually sentenced to death for the murder.
